This is Ganganatha Jha's translation of Shri Harsha's Khandana Khanda Khadya. Traditionally, there were six schools of Hindu philosophy: Samkhya, Yoga, Nyaya, Vaisheshika, Purva Mimamsa, and Vedanta. Nowadays, almost all Hindus belong to the Vedanta school, the others being dead. Now how does a school of Hindu philosophy die? The work I am uploading here may be part of the answer.
The Khandana Khanda Khadya is a work by the 12th Advaita philosopher Shri Harsha which seeks to refute the Nyaya school. Nyaya school believed that the world was real and that we can learn more about it using various Pramanas or means of knowledge. Advaitins, in contrast, believe that the world is an illusion and that all Pramanas are only valid in the illusory world, not in the ultimate reality. So the Khandana Khanda Khadya seeks to show that all Pramanas are ultimately invalid. This work is often said to have killed off the original Nyaya school, forcing it to regroup as the Navyanyaya school, which was a fusion of the Nyaya and Vaisheshika school. This isn't completely accurate; the fusion of Nyaya and Vaisheshika began with Udayana, against whom Shri Harsha's work is actually directed. Still, the Khandana Khanda Khadya was an influential work in the history of Hindu philosophy.
